Is this a sign of dirty injectors?

Q: I have a 2002 Buick Century with the small v-6. It has about 89,000 miles. Recently I noticed it seems to miss or hesitate when starting off at low speed with just a minimum gas pedal pressure. It runs ok as I give it more gas and at higher speeds. Is this a sign of dirty injectors, and if so what is a good additive to clean them, or is this possibly another issue.
Ken

A: I might consider another issue. First, do you have a check engine light on? If so, what is the code? When was the last tune up done (plugs/wires)? Quite often cleaning the Mass Air Flow sensor will take care of low speed hesitations. Another possibility is a dead spot in the throttle position sensor. If you feel an actual misfire, then I would take a look at the ignition system. The misfire could be slight enough that the computer has not picked it up yet. If you decide to take it to a shop, you could expect to spend about $100 to diagnose this problem. As far as fuel additives are concerned, there is nothing strong enough that you can put in your tank to clean them. There is special equipment and chemicals that are used for cleaning injectors.
